Hi Don -- got to admit that it gets a little intense with the whitey's coming by just a foot or two away -- but that's why they pay us wildlife photogs the big bucks right (to you Canadians it would be the big loons, I suppose)? But so long as you know what the risks are, you manage them appropriately, and you are willing to accept the consequences then it is all good. Incidentally, have posted detailed tips on taking the over/under shots on my blog: www.tecshots.com/blog. Cheers, Andrew
